WINDOW.

Application led February 7, 1927. Serial No. 166,517.

The invention relates to windows and refers more particularly to thattype having a sash and ventilator. One of the objects of the inventionis to provide a mountingupon the sash for the Ventilator whichautomatically operates to move the ventilator toward the sash uponclosing of the ventilator. Another object is to provide a 'simple pinless type of mounting permitting of readily detaching the ventilatorfrom the sash. With these as well as other objects in view, theinvention resides in the novel features of construction and combinationsand arrangements of parts as more fully hereinafter set forth.

In the drawings z*- Figure 1 is a plan View of a window embodying myinvention;

Figures 2 and 3 are cross sections on the lines 2-2 and 3 3 respectivelyof Figure l.

The window herewith shown is a basement window and has the metallic sash1 and the ventilator 2 with metallic bars, the ventilator being mountedupon the sash to swing and upwardly. The pivotal mounting upon the sashfor the ventilator includes the mounting members 3 which are pivotallysecured to the web 4 of the head bar of the sash by means of the pivots5 which allow the mounting members to swing through horizontal paths.Each mounting member has at its inner end the hook 6 which extendsdownwardly and inwardly throughthe inclined aperture 7 in the ventilatorhead bar and also through the aperture 8 formed in the inner transverseiange 9 of the ventilator head bar, the metal at the outer edge of theaperture forming a pintle 10. Each hook extends upwardly and terminatesat a distance from the inner transverse flange l1 of the sash head barsufficient to permit readily detaching the ventilator from the sash. Tomove the head bar of the ventilator outwardly toward and into engagementwith the head bar of the sash upon the closing of the ventilator, eachpintle is inclined upwardly and inwardly and has its end positioned toengage the inner surface of the engaged hook to cam the ventilator headbar toward the sash head bar upon closing of the ventilator. Theapertures in the inner transverse flange ofthe ventilator head bar areformed by punching and the pintles are inclined by twisting. l

From the above description it will be seen that I have provided amounting upon the sash for the ventilator which is very simple inconstruction and may be cheaply manufactured. It will also be seen thatthis mounting permits of readily detaching the ventilator from the sash,is pinless and provides for a cam action to move the ventilator towardthe sash upon closing of the ventilator. It will be further seen thatthe mounting provides for adjustment of the ventilator relative to thesash so that the two may properly engage.

What I claim as my invention is:

l'. In a window, the combination with a sash having a head bar formedwith an elongated slot adjacent the inner edge thereof, of a swingingventilator having a head bar with an inner transverse flange formed withan elongated slot in alignment with the slot aforesaid, a memberpivotally mounted upon the head bar of the sash having a hook at the endthereof extending through the said slots, the upper edge of the slot insaid ventilator head bar being turned inwardly forming a pintle for saidhook operable to automatically move said ventilator head bar toward saidsash head bar upon closing of said ventilator.

2. In a window7 the combination with a sash and swinging ventilator7 ofa pivotal mounting upon said sash for said ventilator, including amember pivotally mountedupon said sash to swing in a directiontransverse to that of said ventilator, and means upon said ventilatorhaving a cam engagement with said member to move said ventilatorrelative to said sash upon swinging of the latter.

In testimony whereof I aiiix my signature.
